A groundbreaking commercial release that fully unleashes the allure of femboys is here, offering fans of this genre an entirely new experience. Welcome to a world of limitless possibilities beyond gender. The heroine of this work is a popular "handsome guy-loving beautiful girl cosplayer" from the doujin scene. Yet, contrary to her appearance, an unexpected twist awaits. Enter Yuu-chan (18), who at first seems indifferent, as if drenched in cum. However, at otaku-heavy events where perverts abound, such an attitude is dangerous. She gets dragged into a public restroom by nerds, forced to swallow semen, and nearly subjected to unprepared anal penetration. To escape such situations, she takes refuge in a rental studio. But because she barely speaks, we decide to play a prank on her. Unexpectedly, her skirt begins to bulge—only this time, the swelling looks different. Extremely embarrassed, Yuu-chan hesitantly lifts her skirt to reveal a massive cock lewdly spilling out from her thong. From there, the prank escalates into anal toy torture, followed by double deep throating and full anal sex. One member blasts thick cum directly into her gaping anus, half of it flooding deep into her intestines. As Yuu-chan's desire surges, she begins masturbating herself, triggering an intense, cumshot-filled climax. Later, word spreads and the rest of the circle members gather for Yuu-chan’s first-ever anal gangbang with five men. As everyone stares in shock at her enormous cock, she tightly takes each member’s dick in her ass, revealing a wide-open anal black hole every time a cock pulls out. The sight of backflowing intestinal fluids and ass juice dripping down onto her balls is utterly depraved—an absolute must-see. Don't miss it.
